YAG-39 carried a wash-
Each was instrumented for radiation
Measurements and each carried an unmanned F4U aircraft secured to the
weather deck, also instrumented for radiation measurements.
The ships
were unmanned during the first two shots, with control provided by
P2V5 aircraft, as well as the Molala and possibly the Bairoko.
During
the last two shots, a crew aboard the YAG-39 in a heavily shielded
control room controlled both the YAG-39 and the unmanned YAG-40, with
some assistance from the P2V5 and the Bairoko.
Both ships were taken
to Enewetak for decontamination, with the Instrument Group boarding as
soon as possible to retrieve radiation records.
